Underinflated tyres can mean your engine works harder and burns more fuel.

In fact – over half of UK tyres are under inflated which is costing motorists up to 1 billion pounds a year in excess fuel (1). So, we’re on a mission to help people save by keeping their car tyres pumped up with regular pressure checks. Have you checked yours lately?

Tyres deflate naturally at the rate of 2 PSI per month (2) – so it’s important to check your pressure monthly. Be sure to check and pump before long trips too, that way you’ll have a more fuel efficient and safer journey.

Find your car’s tyre pressure

Every car tyre pressure is different. If you’re not sure about yours – use our easy Kwik Fit tool to find out. (3)

How to use a digital tyre inflator

Naomi Schiff shows how you can check and correct your tyre pressure using a digital tyre inflator to keep you safe on the road and help you save fuel.

    Did you come to one of our pop-up events?

    Together with Kwik Fit, we toured the country during October to help UK motorists check and adjust their tyre pressure. During the two-week activation there were free tyre checks offered at 25 Esso sites, with 1,263 car checks done and 3,842 tyres inflations completed!

Fuel saving may vary depending on factors such as the level of PSI underinflation, type of fuel used, cost of fuel, and/or annual mileage. For details on how the calculations were done, please see this table.

Data from Esso / Kwik Fit and Michelin October 2022 roadshow activations showed 71% of drivers were more than 4 PSI under the optimal pressure - broken down as: 23% of cars we assessed had very dangerous pressures (-15 psi); 28% of cars we assessed had dangerous pressures (-8 to -12 psi); 20% of cars we assessed had temporarily acceptable pressures (-4 to -7 psi)
